Idle hunting

[Dusted74]

So my setup is 05 magnum 5.7. Twin turbo, bla bla bla.
Anyway, its not dialed in dead nuts yet but i have this hunting idle. 600ish to 900ish. Just played with it, disabled closed loop and tuned in the afr to a pretty solid 14.7ish. My eq error was within 1% so i called it good. Idled very smooth at the commanded 750rpm, within 20rpm or so.

As soon as i enable closed loop, hunting is back. No changes other then the temp for closed loop. Hunts bad.

I have most of the timing tables set to 14 in any of the idle areas to try and stabilize it there also.

My ltft is also showing lean by 3-5%(some reason it is a bit off bank to bank)

Probably need to play with transport delay etc...

Where is your wideband located versus your upstream 02 sensors? And where are the upstream sensors located in relation to the exhaust manifold?

Depending on your answer to the above, try tuning the idle AFR in open loop to around 13.5 or so, then turn closed loop back on and see how it acts.
